ALEXANDER APPLEBY, OF BROMFIELD, MAINE.

IMPRIOVELD APPARATUS FOR TANNING.

Specilcation forming part of Letters Patent No. 59, l5?, dated October 30, 1866.

To all whom it may concern.-

Be it known that I, ALEXANDER APPLEBY, of Bromtield, in the count-y of Oxford and State ot' Maine, have in-vented a new and useful or Improved Drum for Handling Hides in the process of tanning them; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure l is a longitudinal section, and Fig. 2 a transverse section, ofthe said drum. Fig.

- 3 is a front elevation, with some of the shrouding removed in order to exhibit the end-grated mouths and the inclined partit-ions. Fig. 4 is an end view ofthe drum.

In these drawings, A A are two circular heads, which are in the form of wheels, having open spaces a a a a between the spokes b b b b. A journal, c, projects from the hub of each of the said heads. rThe two heads or wheels A A are connected by a shrouding, B, which envelops their eireumferences, and is perforated or has a series of inclined slots, cl d d, made in it and arranged at equal distances apart. There is also amouth in the shrouding, which is provided with a hinged door, O, such mouth being to enable the hides to be' either placed within or removed from the drum, as circumstances may require.

Across the drum, and next to each of its heads, I carry an inclined partition, D, such partitions being arranged within the drum in' manner as represented in the drawings. A quadrant, D', of this partition is inclined in an opposite direction or stands at an acute angle wh the rest of the partition, and there is at the opening E between the two a grating or series of slats, as shown at F. These partitions are parallel, or about so.

The wheel or drum so made is intended to revolve within a vat for holding the tanningliquor. While it may be `charged with hides and in revolution in the liquor the hides will not only be turned or rolled over and over, but by means of the inclined partitions the)r will have a reciprocating motion imparted to them-that is, they will be caused to move rst toward one head and next toward the other head of the drum.

These `reciprocating movements of the hides are to prevent them from balling or packing together, and to better expose them to the action of the liquor, which, besides passing into the wheel through some ot' its peripheral openings and out otit through others ot' them, will be forced into it through the grated mouths E E.o The action ot' these mouths on the liquor will be such as to cause it to rush into the wheel through them, and in such manner as to pass into or among the hides to excellent advantage.

This drum so made can be used also in either of the processes of liming or drenehing the hides.

rhe great advantage of my drumover others in use for the purpose is, that it so floats the hides and forces the liquor into the mass as to prevent any bruising or tearing of them, such as they are lia-ble to with various other tanning wheels or drums.

p Nhat I claim as my invention is- 1.' The hide-handling drum as made with inclined partitions, combined with and arranged within it, for the purpose of producing reciprocating movements of the hides while the drum may be in revolution, as stated.

2. The arrangement of the grated mouths E in the drum, and with its inclined partitions, substantially as specified.

ALEXANDER APPLEBY.
